The practical value of the dissertation work is that the methodology

developed on a modern scientific and methodological basis forms the basis of

engineering methods for predicting the safe operation of structures (both at the

design stage and during operation) that work in contact with hydrogen-containing

environments, which indicates its practical value.

Based on the results of the research, 14 scientific works were published,

including 4 articles in specialized scientific publications (including 2 articles in

periodical scientific publications included in the international scientometric

databases WoS or Scopus), 5 theses and reports in collections of conference

materials, 1 author's computer program certificate.

Keywords: hydrogen diffusion, hydrogen concentration, hydrogen-containing

environment, hydrogen decohesion, dislocation movement, local plastic

deformation, mathematical model, crack propagation, residual longevity.
